SPEGIFlCATION forming' part of Letters Patent No.. 529,618, dated November 20, 1894.

.Application filed Pebruary26,1894i Serial No. 501,546) (No model.)

To @ZZ whom, it' may concern,.-

Be n known than we,LoU1s E. HOY andk HARMAN HOY, of Silver Creek, county of Polk,

State of Nebraska, have invented certain new is an end elevation of a car with our apparatus in place. Fig. 2 is a side view thereof. F1g.3 is across section. Fig. 4 is an end view of our apparatus, showing the car elevated.

Referring to the figures on the drawings:

1 indicates a section of track and 2 a dumping frame bridgingthe same.

3 indicates an elevated obstruction in the track located and measured so as to till the space between the wheels 3a of a car trav'e1 ing on the track.

4 indicates the stanchions Aprojecting upwardly from the axles 5 of the car.

6 indicates the end pieces of a swinging frame which are pivoted, respectively, asini dicated at 7, to the upper beams and cross piece 8 of the frame.

9 indicates a coupling piece pivotally united to the end pieces of the swing frame and serving to cause them to move in unison. It is extended at one end and bent to forma hook` that may engage with either end of a catch 11 secured to the cross piece 8. The end pieces 6 of the frame are located so that when they are swung at right angles to the cross the engagement of the swinging frame with the stanchions. To limit the movement of the swinging frame to a position directly over the stanchions, we provide upon one of the end pieces of the frame a depending stop piece 12 which strikes the side of the stanchion and determines the position of the frame. A swinging frarneis preferably provided on opposite sides of the dumping fra-me so that, when both are set in position, they alord between them 'guideways for the elevation of the box 13 of the car. i p

14 indicates a dumping platform adapted to receive the load of the car at the upper limit of its travel, as indicated in Fig. 4. 15 indicates pulley guide-ways adapted to receive the guide pulleys 16 securely pivoted, respectively, in suitable frames in the-middle of each end of the car. The guideways are turned, as illustrated, so as to guide the pulleys from a vertical into a nearly horizontal direction. y

17 indicates projecting studs firmlysecured to the bottom of the car. They have reduced necks 19 adapted to enter the jaw 2O of a pulley plate 21. The jaw 2O communicates with a circular aperture 22 and is itself preferably downwardly inclined, as illustrated, for convenience of attaching the plate to the studs. When the end of the stud enters the aperture in the pulley block plate it is securely held and'free to revolve as long as there is an upward tension upon the pulley block.

23 indicates ropes securely fastened to tlie upper ends of standards 24, which afford seats for the pulley guides. The ropes are two in number and are passed, respectively, around the pulleys 25 of the pulley blocks; thence ascending, each passes over guide pulleys 27 securely carried between uprights 28. Other guide pulleys 29, for example, conduct the ropes away to a suitable elevating power, not illustrated.

` 30 indicates vertical stud gides, which serve to keep the studs in vertical line after being elevated by the action of the pulley ropes. lt will be perceived, therefore,'that while the draft on the car excrtsits influence upon the studs and in line with the pulleys as long as the pulleys are vertically above therstuds, yet, when the pulleys, following their ways, are carried out of the-vertical position, the studs continue to ascend vertically and upset the car upon the pulleys as an axis, thereby discharging the load upon the platform.

When the power upon the pulley rope is released, the box of its own weight, guided by the pulleys descending through their ways,.

will return to the car and be ready for removal, to accomplish which all that is necessary is to nnship the pulley blocks from the studs and to turn the swinging frames outl of the way.

To insure the proper reseating` of the car, after dumping, cleats 3l upon its sides may be provided in proximity to the stanchions.

We do not confine ourselves to the details of construction herein shown and described, but reserve the right to modify and vary them at will Within the scope of the invention.

That we claim is- 1. The combination with a frame, track, obstruction thereon, and elevating mechanism, of a car provided with a detachable box and a horizontally swinging frame adapted to be swungr above the car and prevent its rising over the obstruction and to act as a guide for the box when the same is elevated, substantially as specified.

2. The combination with a frame, track, obstruction and elevating mechanism, of a car provided with stanchions and a detachable box, and a horzontallyswinging frame adapted to be swung above the stanchions of the car and stop mechanism adapted to retain the frame and stanchions in line whereby the stanchions and frame act as continuous guides for the box when the same is elevated, substantially 4as specified.

3. The combination with a trame, of a car having centrally located terminal pulleys and studs secured to and below said pulleys, hoistingr mechanism pivotally secured to the studs, pulley ,guide-ways deflected, as shown, and Eertical stud guides, substantially as speci- 4. The combination with a frame, of a box provided with terminal studs, pulley blocks provided with plates having,l jaws and apertures communicating therewith and block elevating mechanism, substantially as specitied.

5. rlhe combination with a frame, track, obstruction thereon and a plurality of swinging frames, of pulley ways deiiected, as shown, stud guides, a car provided with terminal pulleys and studs adapted to engage the pulley- Ways to stud guides, respectively, pulley blocks adapted to engage the terminal studs and a means for elevating the pulley blocks, substantially as specified.

In testimony of all which We have heren nto subscribed our names.
